Two field trials were carried out during the two successive summer seasons of 2002 and 2003 in South AL-Tahrir sector, AL-Behaira Governorate, Egypt to study the effect of phosphorus fertilizer rates (30 and 60 kg P2O5/fad and foliar spraying with zinc (tap water (control), 0.50, 0.75 and 1.00g/L) on growth, yieldand its components as well as seed quality of groundnut (Giza 6 cv) grown in newlyreclaimed sandy soil. The results showed that increasing rate of phosphorus fertilizer from 30 to 60 kg P 2O5/fad significantly increased vegetative growth, yield and its components as well as seed quality i.e. protein content and NPK percentages, while oil percentage did not reach to the level of significant by increasing the P rate. Foliar spraying with zinc levels had a significanteffect on groundnutgrowth, yield and its components as well as seed quality. It was observed that the most of the characters under study increased significantly by the interaction between phosphorus fertilizer and foliar spraying with zinc expect dry weight of stem, P and oil percentages. It could be concluded that the highest yields of seed, oil and protein (1408, 633 and 368 kg/fad), respectively were obtained by application of 60 kg P2O5/fad with foliar spraying with 1.00g/L zinc.
